| Kai's verdict | B-tier. Still early. Manus is more flexible for less money. | A-tier for sales teams. B-tier for solo users. | S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement. | S-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time. |
